David,
Thanks for the input. The platform that I am currently testing is
T5120/5220. It does not have any PCI slots. It has three PCI-Express
slots. The Radeon(XVR-100) supported by Sun is a PCI card. I have not
been able to locate a PCI-Express version of the card. Sun supports a
different version of Radeon family that is based on [FireGL V3100 (PCIE)
- RV370 5B64]. It is called XVR-300. it works on T5120 platforms running
solaris. There is a strong interest to get this card working on T5120
and the future RDK platforms. it also seems that there is a support for
this card in the linux under (radeon_base.c). I tried this card a couple
of times using two different versions of Linux kernel (stock Ubuntu and
custom built based on source_2.6.24). However, the system hangs during
boot regardless of output-device= screen or virtual-console. I built a
new kernel without the Radeon driver and was able to boot. No hard hang
there. Any inputs appreciated.

I have a SPARC T2000 system installed with Ubuntu 7.10 Server Edition
running "2.6.22-14-sparc64-smp" kernel.
I am interested to know whether anyone knows of any low power PCIe
graphics card and corresponding driver that works on T1000T2000 SPARC
based platforms.
I also tried Nvidia (NVS440) graphic card without the FCODE to see if
I can start X using the nvidiafb.ko driver that comes with stock Ubuntu
kernel distribution for servers. The device was recognized OK. However,
there is a fatal mmap() failure.
NVIDIA isn't going to work, Radeon (XVR-100) cards should
work if you configure X to use the "fb" acceleration-less
driver.
The state of X is very poor under Linux at the moment,
although it should improve substantially in future
releases.
